Cut-in Pressure: While the motor
is off, air tank pressure drops as you
continue to use your accessory. When
the tank pressure drops to a certain
low level the motor will restart auto-
matically. The low pressure at which
the motor automatically restarts is
called "cut-in" pressure.
Cut-Out Pressure: When an air com-
pressor is turned on and begins to
run, air pressure in the air tank begins
to build. It builds to a certain high
pressure before the motor automati-
cally shuts off, protecting your air tank
from pressure higher than its capacity.
The high pressure at which the motor
shuts off is called "cut-out" pressure.

KNOW YOUR AIR COMPRESSOR
READ THIS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with
the location of various controls and adjustments. Save this manual for future ref-
erence. On/Auto/Off
On/Auto/Off Switch: Turn this switch
"On/Auto" to provide automatic power
to the pressure switch and "Off" to
remove power at the end of each use.
Pressure Switch: The pressure switch
automatically starts the motor when
the air tank pressure drops below the
factory set "cut-in" pressure. The pres-
sure switch stops the motor when the
air tank pressure reaches the factory
set "cut-out" pressure.
Safety Valve: Ifthe pressure switch
does not shut off the air compressor
at its "cut-out" pressure setting, the
safety valve will protect against high
pressure by "popping out" at its fac-
tory set pressure (slightly higher than
the pressure switch "cut-out" setting).
Outlet Pressure Gauge: The outlet
pressure gauge indicates the air pres-
sure available at the outlet side of the
regulator. This pressure is controlled by
the regulator and is always less than or
equal to the tank pressure.
Tank Pressure Gauge: The tank pres-
sure gauge indicates the reserve air
pressure in the tank.
Regulator: Controls the air pressure
shown on the outlet pressure gauge.
Pull the knob out and turn clockwise
to increase pressure and counterclock-
wise to decrease pressure. When the
desired pressure is reached push knob
in to lock in place.
Universal Quick-Connect Body: The
universal quick-connect body accepts
the three most popular styles of quick-
connect plugs: Industrial, automotive
(Tru-flate), and ARC. One hand push-
to-connect operation makes connec-
tions simple and easy.
Drain Valve: The
drain valve is
located at the
base of the air
tank and is used
to drain conden-
sation at the end of each use.
Cooling System (not shown): This
compressor contains an advanced
design cooling system. At the heart of
this cooling system is an engineered
fan. It is perfectly normal for this fan to
blow air through the vent holes in large
amounts. You know that the cooling
system is working when air is being
expelled.
15- ENG 1000003598

Air Compressor Pump (not shown):
Compresses air into the air tank.
Working air is not available until the
compressor has raised the air tank
pressure above that required at the air
outlet.
Check Valve: When the air compres-
sor is operating, the check valve is
"open", allowing compressed air to
enter the air tank. When the air com-
pressor reaches "cut-out" pressure,
the check valve "closes", allowing air
pressure to remain inside the air tank.
Pressure
Release
Check Valve
Pressure Release Valve: The pres-
sure release valve, located on the side
of the pressure switch, is designed to
automatically release compressed air
from the compressor head and the
outlet tube when the air compressor
reaches "cut-out" pressure or is shut
off. The pressure release valve allows
the motor to restart freely. When the
motor stops running, air will be heard
escaping from this valve for a few
seconds. No air should be heard
leaking when the motor is running or
after unit reaches "cut-out" pressure.
Air Intake Filter (not shown) This
filter is designed to clean air coming
into the pump. This filter must always
be clean and ventilation openings free
from obstructions. See Maintenance.
Motor: This motor has a manual ther-
mal overload protectoE If the motor
overheats for any reason, the overload
protector will shut off the motor. The
motor must be allowed to cool down
before restarting.
To restart:
1. Place the
On/Auto/Off
lever in the
"Off" pos-
tion.
2. Allow the
motor to
cool.
3. Depress the
red reset button on the motor.
4. Place the On/Auto/Off lever in the
"On/Auto" postion to restart the
motor.

'""__ Operation. Unit
cycles automatically when power
is on. When servicing, you may
be exposed to voltage sources,
compressed air, or moving parts.
Before servicing unit unplug or
disconnect electrical supply to
the air compressor, bleed tank
of pressure, and allow the air
compressor to cool.
To ensure efficient operation and lon-
ger life of the air compressor, a routine
maintenance schedule should be pre-
pared and followed. The above routine
maintenance schedule is geared to an
air compressor in a normal working
environment operating on a daily basis.
If necessary, the schedule should be
modified to suit the conditions under
which your air compressor is used.
The modifications will depend upon
the hours of operation and the work-
ing environment. Compressors in an
extremely dirty and/or hostile environ-
ment will require a greater frequency of
all maintenance checks.
NOTE: See Operation section for the
location of controls.
TO CHECK SAFETY VALVE
_Risk of Bursting.
__ if the safety valve
does not work properly, over-
pressurization may occur, causing
air tank rupture or an explosion.
_Risk from Flying
Objects. Always
wear certified safety equipment:
ANSI Z87.1 eye protection (CAN/
CSA Z94.3) with side shields.
1000003598 18-ENG

Before starting compressor, pull the
ring on the safety valve to make sure
that the safety valve operates freely. If
the valve is stuck or does not operate
smoothly, it must be replaced with the
same type of valve.
TO DRAIN TANK
_Risk of Unsafe
Operation. Risk
from noise. Air tanks contain high
pressure air. Keep face and other
body parts away from outlet of
drain. Use ANSI Z87.1 eye protection
(CAN/CSA Z94.3) when draining as
debris can be kicked up into face.
Use ear protection [(ANSI $12.6
(S3.fg) hearing protection] as air
flow noise is loud when draining.
1. Set the On/Auto/Off switch to
"Off".
2. Pull the regulator knob out and
turn clockwise to set the outlet
pressure to zero.
3. Remove the air tool or accessory.
4. Pull ring on safety valve allowing
air to bleed from the tank until
tank pressure is approximately 20
PSI. Release safety valve ring.
5. Drain water from air tank by open-
ing drain valve on bottom of tank.
_Risk of Bursting.
Water will
condense in the air tank. If not
drained, water will corrode and
weaken the air tank causing a risk
of air tank rupture.
_Risk of Property
Damage. Drain
water from air tank may contain oil
and rust which can cause stains.
6. After the water has been drained,
close the drain valve. The air com-
pressor can now be stored.
NOTE: If drain valve is plugged,
release all air pressure. The valve can
then be removed, cleaned, the rein-
stalled.
OIL
_This compressor
was shipped with
oil in the pump crankcase. Check
oil before operating air compressor,
see Check Oil under Maintenance.
Risk of Bursting.
Drain tank to release
air pressure before removing the oil
fill cap or oil drain plug.
Use air
compressor oil
only. Multi-weight automotive
engine oils like t0W30 should
not be use in air compressors.
They leave carbon deposits on
critical components, thus reducing
performance and compressor life.
Checking
1. Place unit on a level surface.
2. Remove the oil fill plug (A). The oil
level should be even with the top
of the fill hole and no lower than 6
threads from the top of fill hole.
2. If needed, slowly add oil until it
reaches the top of fill hole.
NOTE: Use 30W compressor oil or
a heavy duty SAE 30W, non-deter-
gent, SF grade or better oil DO NOT
use multi-weight automotive engine
oils, they will reduce compressor life.
Under extreme winter condition use
SAE-10 weight oil.
Changing
1. Place unit on a level surface.
2. Remove the oil fill plug (A).
3. Remove the oil drain plug (B) and
drain oil into a suitable container.
4. Replace the oil drain plug (B) and
tighten secure.
19-ENG 1000003598

NOTE: Use 30W compressor oil or a
heavy duty SAE 30W, non-detergent,
SF grade or better oil DO NOT use
multi-weight automotive engine oils,
they will reduce compressor life. Under
extreme winter condition use SAE-10
weight oil.
5. Slowly fill crankcase to the top of
the fill hole. NOTE: Crankcase oil
capacity is approximately 16 fluid
ounces (0.5 L).
6. Replace oil fill plug (A) and tighten
securely.
AIR FILTER INSPECTION AND
REPLACEMENT
Risk of Burns,
Compressor head
and cylinder sleeve are very hot. Do
not touch. Allow compressor to cool
prior to servicing.
A dirty air filter will not allow the com-
pressor to operate at full capacity.
Keep the air filter clean at all times.
1. Remove the air filter cover.
2. Remove the air filter from filter
cover.
IMPORTANT: Do not operate the
compressor with the air filter removed.
3. Place new air filter into filter cover.
Refer to the "Repair Parts" for the
correct part number.
4. Replace air filter cover and lock
into place.
MOTOR PULLEY/FLYWHEEL
ALIGNMENT
NOTE: Once the motor pulley has
been moved from its factory set loca-
tion, the grooves of the flywheel and
pulley must be aligned to within 1/16"
(1.6 mm) to prevent excessive belt
wear.
The air compressor flywheel and motor
pulley must be in-line (in the same
plane) within 1/16" (1.6 mm) to assure
belt retention within flywheel belt
grooves. To check alignment, perform
the following steps:
1. Unplug air compressor from
power source.
2,
3.
4,
Remove belt guard.
Place a straightedge against the
outside of the flywheel and the
motor drive pulley.
Measure the distance between
the edge of the belt and the
straightedge at points A1 and A2
in figure. The difference between
measurements should be no more
than 1/16" (1.6 mm).
5. If the difference is greater or less
than 1/16" (1.6 mm) loosen the
set screw holding the motor drive
pulley to the shaft and adjust the
pulley's position on the shaft until
the A1 and A2 measurements
are within 1/16" (1.6 mm) of each
other.
6. Torque the motor drive pulley set
screw to 70-80 in.-Ibs.
7. Visually inspect the motor drive
pulley to verify that it is perpen-
dicular to the drive motor shaft.
Points B1 and B2 of Figure should
appear to be equal. If they are
not, loosen the setscrew of the
motor drive pulley and equalize B1
and B2, using care not to disturb
the belt alignment performed in
step 2.
8. Retighten the motor drive pulley
setscrew to 70-80 in.-Ibs.
9. Reinstall belt guard.
